UNITED STATES PATENT OFFICE.

JOHN S. B. PATTERSON, OF BALTIMORE, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO WILLIAM GEORGE HOFF, OF CLIFTON, MARYLAND.

COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 229,453, dated June 29, 1880. Application filed October 10, 1879.

To all whom it may concern:

Be itknown that I, JOHN S. B. PATTERSON, of the city of Baltimore and State of Maryland, have invented certain Improvements in Copy- Holders, of which the following is a specification; and I do hereby declare that in the same is contained a full, clear, and exact description of my said invention, reference being had to the accompanying drawings, and

to the letters of reference marked thereon.

This invention relates to a device to be used by public speakers and others to hold manuscript in such manner as to admit of any part of its contents being readily referred to withr 5 out the necessity of turning over leaves.

In carrying out my invention I employ a suitable frame having a revoluble roller at either end thereof, which rollers are provided with pulleys, over which an endless propelling 2o cord or belt is placed.

The sheets of manuscript are pasted together to form a single strip, which is at its ends attached to the rollers aforesaid. In reading the strip is gradually transferred from the lower to the upper roller by means of the endless propelling-cord, and it will be seen that any passage in the manuscript can be readily referred to by turning the rollers in the proper direction.

The invention consists in certain details of construction, as hereinafter set forth.

In the further description of my said invention, which follows, reference is made to the accompanying drawings, forming a part 3 5 hereof, and in which Figure I is a face view of the invention, and Fig. II is a longitudinal section of the same.

Similar letters of reference indicate similar parts in both the views.

A is the frame of the device, consisting of a board having supports a at its ends for the rollers B. The supports a are made of sheet metal, nearly cylindrical, and provided with bearings a, of wood or suitable material, in

5 which the pins of the rollers rest. The said rollers are removable, to allow of the attachment of the manuscript, which, in the drawings, is represented by G.

D D are strips attached to the frame in such manner as to protect the edges of the paper between the rollers. Each roller B is fitted with a pulley, a", and the two pulleys are connected by an endless propelling-cord, b.

The rollers are held within their bearings by means of pins, as shown, but any other securing device may be used without affecting the nature of my improvement.

The manuscript is first wound upon the lower roller and the free end thereof attached to the upper roller. The rollers and manu- 6o script are then introduced to the frame A, and after a proper tension is placed upon the manuscript by revolving the lower roller independently of the upper one the pulleys a are connected by the endless band b.

To operate the device the endless propelling-cord is moved in such direction as to transfer the manuscript from the lower to the upper roller, and the speed with which it is moved is regulated to suit the reader.

The convenience of this device will be readily understood and appreciated by public speakers and others who heretofore have either read from loose leaves or manuscriptsheets attached together in the usual manner.

I am aware that revoluble cylinders have been placed in a box, and the same provided with an endless strip carrying pictures, whereby the pictures are made to appear in succession by turning one of the cylinders by means of a suitable handle.

I am also aware that such cylinders have been geared together to give them a combined movement; but the first-mentioned device is not applicable to my purpose, as in it the strips are not held tightly between the cylinders, except by being forced against a glass plate; and in the second, where gearing is used, the cylinders are practically not removable, and their relative adjustment, after 0 the strip is secured thereto, cannot easily be attained.

In my invention, however, the propellingcord can be detached at any time to allow of the stretching of the manuscript. 5

I claim as my invention The frame A, supports a, bearings a, and detachable rollers B, provided with pulleys a, combined with the strips D and propellingcord b, substantially as specified.

JOHN S. B. PATTERSON.
